Zorluk: KolaySmart Motorways and Active Traffic Management

On a smart motorway with a dynamic hard shoulder, how can you tell that the hard shoulder is open to traffic as a running lane?

  1. A speed limit is displayed on the overhead gantry above the hard shoulderCevap
  2. B
    A red 'X' symbol is illuminated on the overhead gantry above the hard shoulder
  3. C
    The overhead gantry signal directly above the hard shoulder is blank
  4. D
    Amber flashing lights are active on the verge beside the hard shoulder

Cevap

A speed limit is displayed on the overhead gantry above the hard shoulder
On smart motorways featuring a dynamic hard shoulder, the hard shoulder is opened as a live running lane only when a speed limit is displayed on the overhead gantry directly above it. If the sign is blank or displays a red 'X', it remains closed to regular driving.

Adım Adım Çözüm

1
Identify the operational rules for a dynamic hard shoulder
Recognise that a dynamic hard shoulder functions as an emergency-only lane unless electronic signage indicates otherwise.
Under UK Highway Code Rule 269, dynamic hard shoulders are only open when designated by active electronic gantry signals.
2
Evaluate the meaning of overhead gantry indicators
Confirm that an illuminated speed limit sign above the lane designates it as open to traffic.
Displaying a speed limit above the hard shoulder authorises drivers to use it as a standard running lane to improve traffic flow.
